Fuel Tank Cleaning and Gas Freeing

Tank Cleaning is essential to the maintenance and lifespan of your tank.  Make sure you get your tank the care it needs and read more.

Storage tanks used for fuel oils such as diesel, gas-oil, kerosene and petrol will, over time, build up a layer of contamination. For example, condensed water build ups form sludge and a muddy layer in the bottom of the tank. Therefore, this build-up over time will start to cause problems down the line with filters blocking, fuel lines clogging, engines stopping, boilers coking up and inevitable downtime.

As tanks begin to empty of their contents that introduce air and space into the tank. Some of the lighter chemicals in the oil or fuel begin to vaporise. This Fuel Air mixture can be more volatile than the fuel itself due to the oxygen introduced into the gas. Our highly trained professionals have advanced cleaning systems that give them a couple of options. Inerting or Purging the gas with high pressure, pushing the fuel-air mixture out of the tank. That can either be replaced by an inert gas or assessed to check that the tank atmosphere is deemed safe. These Industrial Tank Cleaning techniques are most relevant to removing the tanks after removal of the fuel. It also applies to change of product within cargo tanks, chemical tankers and oil tankers where cargo vapour may contaminate the new product.
